It seems that no concept that the mind can hold within it will be able to explain the nature of Ultimate Reality.
A Map of Reality
Humans want to know what's real, what's reality, what's true. We have explored the outside world and our inner worlds for millennia, and we seem to still not be sure what is absolutely real. I think the issue might be that what is really real is not something that can be seen or communicated through language at our dualistic level of perception. We have to transcend duality experientially and consciously in order to know the "really real," sometimes called the Nondual, the One, the Real, the Absolute, or God. Perhaps only at that level of consciousness may we come to truly know what is ultimately Real and True.
Mapping The World's Religious and Secular Symbols
At times I feel like much religious terminology and symbolism has failed to bring unity to our modern culture and global society, and that we need new terms and symbols to point to these highest realities for which we yearn. New religious movements often emerge under such conditions (and there are tens of thousands of these movements in the world today). But I'm not sure that helps, but just further divides us, each believing they have "the truth."
